I have a 220V electric dryer and it stopped heating...the drum and fan worked. I went to fix it and in the process of turning the circuit breaker on and off a few times and taking the front panel off to look at the heater element and thermostats ...it started heating. Is there a known failure mode of a 220V circuit breaker failing on one of the phases and allowing for something like this to happen???...and if so how do I check a circuit breaker for proper function...are they very hard or expensive to replace?...maybe I should just replace them.
